A fifteen-second product video is long enough to show the item, say who it is for, and stop. If you are quoting that job this week, or paying someone else to make it, put a number next to the generation before you agree a fee.
Start with one setup you can explain to a client: a text prompt, 720p, 16:9, and no reference clip. A photo, a phone-shaped frame, or a spoken line moves the bill. Price the version you will actually send.
The sum for that setup
On the Seedance 2.5 API, text to video at 720p with no reference video is 0.1965 US dollars a second. Fifteen times that rate is 2.9475 US dollars. The official rate on the same row is 0.2311 US dollars a second, which is 3.4665 US dollars for the same fifteen seconds. The page calls its own rate 15 per cent lower. The rows assume 16:9 and 24 frames a second, and they are refreshed at least daily.
The figure is in US dollars. On a UK invoice, convert it on the day you send the quote. The platform can reserve funds when the task starts, then settle the charge on actual use, so the invoice line can differ from 2.9475 US dollars.
What moves the number
Text to video on this API runs from 4 to 30 seconds, at 480p, 720p, or 1080p. The same fifteen seconds at 1080p, still with no reference video, is 0.4833 US dollars a second, or 7.2495 US dollars. At 480p with no reference video it is 0.0873 US dollars a second, or 1.3095 US dollars. A longer cut costs more, up to that 30-second text-to-video limit.
A reference video sits on another row. At 720p the listed rate is 0.1175 US dollars a second, against 0.1965 without one. The length of that reference can add cost on top of the headline rate, so read the live quote before you promise a client the lower number.
Three modes are listed: text to video, image to video, and omni reference. The sums above are the text-to-video rows. Starting from a product photo means taking the image-to-video quote before it goes into a proposal. Ratios include 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, and adaptive. This worked example is the 16:9 row. A vertical post needs its own number.
Audio is optional. If the client wants a spoken line, switch it on and read the new quote. The rows above are tied to resolution, ratio, and frame rate.
You get a task id back, then the file when the task finishes. Save the file and read the settled charge. Keep the API key on your server. The Playground copies the prompt so you can confirm length, resolution, ratio, and audio before the paid call. Any free credit is whatever balance the workspace shows that day. The generation is paid from that balance.
One video from a product page
When the job is one marketing video this week, open Topview. Describe the idea, or add a script, a reference video, or the product URL. It plans the scenes, picks the models, makes the assets, and keeps the shots editable. The URL can start a marketing video of that product. You send the file to the client.
Write 2.9475 US dollars into the quote only when the job really is fifteen seconds, 720p, 16:9, text to video, and no reference clip. Anything else gets a fresh number the same day. Add your own hours on top of the generation line.
Use a product and a page you are allowed to show. The result is a generated clip for the offer, not a camera on a customer’s table.
